/** \class MaximumEntropyThresholdCalculator
* \brief Computes the MaximumEntropy's threshold for an image.
*
* Implements Kapur-Sahoo-Wong (Maximum Entropy) thresholding method
* Kapur J.N., Sahoo P.K., and Wong A.K.C. (1985) "A New Method for
* Gray-Level Picture Thresholding Using the Entropy of the Histogram"
* Graphical Models and Image Processing, 29(3): 273-285

*
* This class is templated over the input histogram type.
* \warning This calculator assumes that the input histogram has only one dimension.
